Gear reduction question

4159 Views 10 Replies 6 Participants Last post by  Eddiesxs
First off please forgive me I know there is a lot on here about this. But I have watched so many videos and read so much over the last week I have a headache and am now confused and don't want to do this twice. This is my first UTV it's a 2015 XP4 1000. I'm from Northern Cal. and now live in Nor. east Utah. I've been rock crawling my whole life. I'm looking at doing a gear reduction but am confused as to what to buy.
I want the most gear reduction I can get for my rig. I read on the post Gear Reductions - All Models
I just want to confirm that I'm reading this correct that if I buy the parts
XP 1000 4 Seater Options:
#3235764 HL Input Shaft 42T/20T/25T
#3235633 HL Chain
#3235762 Sprocket 48T
#3235232 low Gear 67T
#3235451 25T Ace 325
#3235450 48T Ace 325
That I will get Net reduction: 39.74% Low : 12.69% High : 12.69% Reverse

The lowest price I found is
Total:$877.58
at Discounted OEM Parts & Accessories | Parts Pit Stop

But when I Called a few places they said I can only get a 25% reduction


Any advice not on how to but rather what to buy to get the minimum 25% reduction but would prefer more?
Thank you very much

Are you going to the highlifter shaft for the beefier chain? If so, I'd just up it to a double chain from the get go. If you're doing it for the different gear ratio of the highlifter, I don't have enough experience there to comment.

Also, if you want/need more gear reduction, you can always get it by adding portals.

The Ace 325 gear set provides a 25% reduction across all gears. The HL/TRE low gears add an additional 21% in low only. If you wanted to add the HL/TRE high gear you could change the amount of high gear reduction to only 13%. That's what I did to mine. 46% in low, 25% in reverse and 13% high. Big tires and low gearing are the best money I have spent to increase the capability of my buggy. One problem you might have is being a 2015 I think you have the Team Tied secondary and the input shaft you list is for a BOS secondary. You would have to change your secondary if you use that shaft.

46% in low would be great.

I like portals but the thing is you get gear reduction all around I really don't need it in high If I was taking my rig back to NorCal potals would be the way to go but I think the money for portals I could get a lot more bang for my buck in gear reduction. I'm just finding it hard to get what I want with the 2015. It sounds like 25% is max I can get for a 2015.
Thanks for your input

Can you not do the 53/26/26 reduction listed in the thread that you linked?

That's kind of my question, why would a 2 seater be different than a 4 seater? Maybe they don't have the same transmission or maybe they are geared differently so the reduction % would be different. LDK
@Crash City SxS . I know he will know if someone else doesn't chime in sooner
You already have the 27 tooth reverse shaft and the ranger low gearset in your rzr.

so without going with portals you could do the @SuperATV stage two and stage 3 reduction and get about 26% in all gears more from where you’re at now. And that’s lowest you can go inside trans for your particular year.

I have a 2016 rzr 1000xp with 35"tires... We only go mudding, the most gear reduction i can find is that 38% stage 2 and stage 3? Is there somewhere else I can get more? I'm looking at super ATV on Amazon... Just watched the crash city YouTube videos, looks doable...
